NOTE
Rigid foam insulation is very energy ef-
cient, but is not a sound insulator.
Understanding the sounds you
may hear
Your new, high-efciency refrigerator may
introduce unfamiliar sounds. These sounds
normally indicate your refrigerator is operating
correctly. Some surfaces on oors, walls, and
kitchen cabinets may make these sounds more
noticeable.
IMPORTANT
During the automatic defrost cycle, you may
notice a red glow in the vents on the back
wall of your freezer compartment. This is
normal during the defrost cycle.
Following is a list of major components in your
refrigerator and the sounds they can cause:
A Evaporator Refrigerant through the
evaporator may create a boiling or
gurgling sound.
B Evaporator fan You may hear air being
forced through the refrigerator by the
evaporator fan.
C Defrost heater During defrost cycles,
water dripping onto the defrost heater
may cause a hissing or sizzling sound.
After defrosting, a popping sound may
occur.
D Automatic defrost control These parts
can produce a snapping or clicking sound
when turning the cooling system on and off.
E Compressor Modern, high-efciency
compressors run much faster than in the
past. The compressor may have a high-
pitched hum or pulsating sound.
F Drain pan (not removable) You may hear
water dripping into the drain pan during
the defrost cycle.
